Title: Semiconductor device
Inventor: MORI MIKI
IPC: H01L21/60
Filed: 1990-09-28
Abstract: PURPOSE:To reinforce a bump and improve thermal shock resistance and moisture resistance by sealing the bump with a first resin composition large in flexural elastic modulus, and further covering this first resin composition with a second resin composition small in flexural elastic modulus. CONSTITUTION:The gap between a semiconductor element 11 and an insulating substrate 13 is impregnated with, for example, acid-anhydride-hardened epoxy resin 15 as a first resin composition. This epoxy resin 15 fills up the gap between the semiconductor element 11 and the insulating substrate 13 and seals a bump 12. Next, as a second resin composition, using the silicon resin 16 being the resin composition smaller in flexural elastic modulus than the epoxy resin 15, the epoxy resin 15 and the semiconductor element 11 are covered not to be exposed, and the resins 15 and 16 are hardened at the same time. Accordingly, the bump 12 is reinforced by the epoxy resin 15 large in flexural elastic modulus, and it prevents the moisture, etc., penetrating from the interface between the epoxy resin 15 and the bump 12, and cracks and exfoliation are hard to occur in the outside periphery of the silicon resin 16, and moisture resistance and thermal shock resistance improve.

Title: Controller for inverter
Inventor: ICHIKAWA KOSAKU
IPC: H02M7/48
Filed: 1984-12-10
Abstract: PURPOSE:To make the PWM voltage waveform of an actual output approach to a theoretical waveform by comparing a theoretical reference PWM gate signal of a PWM inverter with the actual PWM output voltage waveform, and correcting it. CONSTITUTION:A reference PWM signal (a) and a voltage waveform signal (b) for detecting the actual output voltage are input to a NAND circuit 72 of a waveform difference detector to detect a waveform difference, thereby obtaining a waveform difference signal (c). A comparator 85 of a correcting circuit compares with the output of a signal read out in a preset counter 84, and outputs a coincidence signal (f) when the counted value coincides. A flip-flop 86 triggered by the rise of a reference PWM signal (a) by the signal (f) is reset to generate an output signal (e). This signal (e) becomes narrower than the pulse width of the signal (a) of the reference PWM to become a corrected signal.

Title: Immersion filter bed type biological treatment apparatus
Inventor: KAWANO KOICHI
IPC: C02F3/06
Filed: 1985-11-21
Abstract: PURPOSE:To easily wash fiber waste, in treating paper or pulp waste water in an immersion filter bed apparatus, by using a granular material having a smooth surface and specific gravity of 0.9-1.5 as a filter. CONSTITUTION:Water to be treated is made to flow in from the holes of a water diffusion pipe 7 through a raw water pipe 5 and air is made to flow in from the holes of an air diffusion pipe 9 through an air pipe 8. By this method, the org. substance in water to be treated is biologically oxidized by the action of aerobic microorganisms grown on a filler bed 4 and treated water from which the org. substance is removed is obtained from an outlet pipe 10 through a trough 11. Because a granular material having a smooth surface and specific gravity of 0.9-1.5 is used as a filler 3, fine fiber waste is hard to be caught by the filler 3. In order to prevent the filter bed 4 from generating clogging during long-term use, washing water is made to periodically flow in from the water diffusion pipe 7 and/or washing air is made to flow in from the air diffusion pipe 9 through the air pipe 8. By this method, drastic saving of washing water is attained to a large extent.

Title: Wet treatment of semiconductor substrate
Inventor: KAWASE YASUYOSHI
IPC: H01L21/304
Filed: 1986-10-31
Abstract: PURPOSE:To prevent floating dust in a liquid from attaching to a wafer when it is taken out from the surface of a treating liquid, by eliminating a process of taking out a wafer from a treating tank during a chemical treatment and a pure water treatment. CONSTITUTION:A semiconductor substrate 19 is treated in a chemical liquid tank 1 filled with a chemical liquid such as acid or alkali, and then pure water is supplied to the chemical liquid tank 1. After the chemical liquid is replaced by the pure water, the substrate 19 is moved to a first pure water tank 2 in a state of being dipped in the water, and is treated with the pure water in the first pure water tank 2. Then the substrate 19 is moved to a second pure water tank 3 in a state of being dipped in the water, and is moved against the flow of the pure water from its lower side to its upper side. At the upper side of the flow, the substrate 19 is taken out to the outside of the tank. The substrate 19 is moved from the chemical liquid tank 1 to the pure water tanks 2 and 3 in a state of being dipped in the water, so that fine particles floating on the surface of the liquid in the tank do not attach to the substrate 19. Thereby the amount of dust attaching to the wafer can be reduced.

IPC: F16J15/3232
Filed: 1993-10-19
Abstract: PURPOSE:To improve the durability of a seal ring and prevent the flow-out of lubricating oil outside a vessel, by installing an air pressure adjusting means which keeps the air pressure at the slightly lower value than the draft pressure and arranging an oil gravity tank at the position where the pressure in an oil chamber becomes slightly higher than the pressure in an air chamber. CONSTITUTION:The air pressure which is supplied into the air chamber 8 formed of the first and the second seal rings 6 and 7 follows the change of the draft water line WL by an air pressure adjusting means 15, and kept at a constant pressure which is set slightly lower than the draft pressure, and further each lubricating pressure in each of the first and the second oil chambers 10 and 9 is set higher than the pressure in the air chamber 8 by the portion corresponding to the lubricating oil head pressure. Accordingly, the blow-out of the compressed air outside and inside the vessel from both the seal rings 6 and 7 is prevented, and since the differential pressure is set small, the life of each seal ring 6, 7 can be prolonged. Further, since the lubricating oil slightly flows into the air chamber 8, the flow-out of the lubricating oil outside the vessel from the air chamber 8 is prevented, and the drainage of the oil and the intruding water flows into a drain recovery tank 18, and can be recovered.

Filed: 1989-10-06
Abstract: PURPOSE:To obtain a proportional solenoid operable in both pushing and pulling directions by winding first and second coils around outer peripheries of first and second bodies fitted to both ends of a plunger sleeve, exciting one coil while exciting correspondent body, and thereby attracting a plunger between both bodies. CONSTITUTION:When electric supply and excitation are performed on a first coil 8, a magnetic circuit is constituted by the first coil 8, a first body 2 and a plunger 10, and attraction force is generated on the first body 2. The plunger 10 moved leftward accordingly, and a spool of a directional control valve connected to a shaft part 11 is pressurized and changed over. When a second coil 3 is excited, attraction force is generated on the second body 3, and the plunger moves rightward. The spool connected to the shaft part 11 is pulled and changed over. It is therefore possible to push and pull the spool of the directional control valve with a proportional solenoid alone.
